我忘记了什么?好像我之前做过的没问题。 当我遍历XmlNodeList时,我想获取每个节点的值,但是我似乎一遍又一遍地获取第一个节点。
string strXpathHL1Loop = "//*[local-name()='HLLoop1']";
XmlNodeList nodeList = xmlDoc856.SelectNodes(strXpathHL1Loop);
Console.WriteLine("Number HLLoop1 nodes=" + nodeList.Count);
int lineNum = 0;
int loopNum = 0;
foreach (XmlNode node in nodeList)
{
loopNum++;
Console.WriteLine("\n-----LoopNum=" + loopNum);
Console.WriteLine(node.OuterXml);
string xpathHL01 = "//HL01";
XmlNode HL01Node = node.SelectSingleNode(xpathHL01);
Console.WriteLine("HL01Node.OuterXml=" + HL01Node.OuterXml);
Console.WriteLine("HL01=" + HL01Node.InnerText);
string xpathHl03 = "//HL03";
XmlNode Hl03Node = node.SelectSingleNode(xpathHl03);
Console.WriteLine("HL03Node.OuterXml=" + Hl03Node.OuterXml);
Console.WriteLine("HL03=" + Hl03Node.InnerText);
}
-----LoopNum=1
<ns0:HLLoop1 xmlns:ns0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006"><ns0:

HL01Node.OuterXml=<HL01>1</HL01>
HL01=1
HL03Node.OuterXml=<HL03>S</HL03>
HL03=S
-----LoopNum=2
<ns0:HLLoop1 xmlns:ns0="http://schemas.microsoft.com/BizTalk/EDI/X12/2006"><ns0:

HL01Node.OuterXml=<HL01>1</HL01>
HL01=1
HL03Node.OuterXml=<HL03>S</HL03>
HL03=S
循环2的预期结果:
HL01=2
HL03Node.OuterXml=<HL03>O</HL03>
HL03=O
这是可复制的最少数据:

答案 0 :(得分:1)
使用相对于node
上下文节点向下的路径,例如
string xpathHL01 = ".//HL01";
或
string xpathHL01 = "descendant::HL01";
您以/
开头的尝试从上下文节点的根节点/文档节点开始搜索/选择,因此每次选择都以相同的节点结束。
